Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

I was trying to pass a car doing a little over 55 mph and heard a loud bang noise. I pulled over and stop the as as quickly as possible. The oil light came on and there was oil was pouring out from underneath the motor. The oil service was kept up to date and was just changed. The car was towed and the engine had thrown a rod. Motor needed to be replace. (after doing some research this seems to be a problem with 4 runner engines when they reach 75000 mles or more. I am not alone in this problem.) I was lucky that I didn't get into an accident and that I wasn't on the expressway in Chicago. I have emailed Toyota.

My 2002 Toyota 4runner has a faulty throttle position sensor (part # 89452-35030) that causes loss of power while driving (at all speeds). This loss of power is very dangerous as the car will be driving along at a stable speed and then suddenly just start slowing down even though my foot stays on the gas pedal. This loss of speed puts me at serious risk to be rear-ended by a car behind me or potentially get hit from the side as I am crossing an intersection. My mechanics and I have diagnosed the tps as the issue. This is a very common problem (there are multiple forums on the web about this). Here are some of them below:"T=16753"T=13283 please get Toyota to issue a recall for this part. It is something that needs to get dealt with before there are more serious incidents. Thanks.
